APS designed, engineered, fabricated and installed various steel elements for the RMIT NAS building for our client Lend Lease Building.

The project entailed design and install of all miscellaneous steel work, full façade steel for the green building, shop front steel and glass, seating bays, lighting trusses, window pods, glazing and skylights, public stairs and feature ceilings.

This required the full suite of welding, fabrication, mechanical, rigging and scaffold supply, erect and dismantle to complete the project on time and safely.


Initially contracted to the Gorgon LNG construction project in 2012, consistent, high-quality work saw the scope and APS site team continuously grow from a small team to 100+ tradesmen and rope access personnel. The complexity of the scope required our workforce to include mechanical fitters, riggers, scaffolders, boilermakers, and electricians, all of whom provided a wide range of specialist services. Working closely with tier one O&G contractors such as Downer, the APS staff provided safe, time and cost-effective mechanical solutions to support the complex construction activities being carried out, delivering our scopes with an outstanding safety record.
